No problem, friend Rathi. Please continue the project
For some reasons, I am not able to test it on Vista right now. Can you please show some image output in Vista? So that, I can understand what it should be.
With best regards.

I just ran the example on my XP netbook but suffered the same problem other users were having with distorted background imagery. I've done some OpenGL programming in the past & was able to solve the problem by adding the following lines in the c_graphics.c file.
